Incorrect type of date/time fields in documentation

[swapy]

I found small issue in documentation where we mention datetime with java.util.Date but in reality spring batch has moved to new java classes java.time.LocalDateTime. So this needs to be fixed in docs.

Places to change:

1. https://docs.spring.io/spring-batch/docs/current/reference/html/index-single.html#jobexecution

• startTime
• endTime
• createTime
• lastUpdated

2. https://docs.spring.io/spring-batch/docs/current/reference/html/index-single.html#stepexecution

• startTime
• endTime

Good catch! Thank you for raising this. Contributions are welcome.
